If the temperature difference range of the heated workpiece is required to be controlled in a small range, the heating area of the parts is bound to be reduced, and the effective area of the corresponding furnace chamber should also be reduced, the furnace can not work at full load, resulting in a waste of energy and man-hours, and the unit consumption of the product will also increase, so the average temperature area of the chamber furnace must be expanded as much as possible.
